AQUATIC HABITATS AND SPECIES IN THE GUNNISON BASIN
Gunnison Basin aquatic habitats range from cold, clear streams at high elevations to warmer, siltier rivers at lower elevations. Trout tend to favor colder water, while the endangered Colorado pikeminnow, razorback sucker, boneytail and humpback chub inhabit the warm waters of the lower Gunnison River. In addition to fish, aquatic insects are important components of aquatic ecosystems.
